mcp-run-python API Security Vulnerability

🚨 High risk vulnerability in Authlib! CVE-2026-28802 allows attackers to bypass signature verification by setting `alg: none` and a blank signature. This issue points out the importance of API security. It's been patched in version 1.6.7, so update ASAP! #Authlib #Python #OAuth #OpenIDConnect #APISecurity #OWASP #CVE202628802 🛡️ https://lnkd.in/g7YS_ka9

Deprecate confusing APIs like “os.path.commonprefix()”. After fixing a vulnerability in #pip, I started digging into the confusing API and found more than I expected. 👉 https://lnkd.in/g5phKjam #python #oss #opensource #security

Another machine pawned on HackTheBox! This one had a really satisfying chain exploited a critical Python vulnerability (CVE-2025-4517) to bypass a security filter that was supposed to be bulletproof, ultimately gaining full root access on the machine. The deeper I go into these challenges, the more I appreciate how a single overlooked detail in code can completely unravel a system's defences.

🚨 High risk vulnerability detected in Fickling, a popular Python pickle file manipulator! The issue (CWE-284) allows an attacker to bypass safety checks via a REDUCE+BUILD opcode sequence, potentially leading to unauthorized access and data exfiltration. This highlights the importance of robust API security and proper access control. Stay safe! #Fickling #Python #APIsecurity #OWASP #CWE284 https://lnkd.in/gWJ3XKWy

🚨 High Risk Alert! 🚨 Authlib, a popular Python library for OAuth and OpenID Connect, has a critical vulnerability (CWE-347). A malicious JWT with 'alg: none' and an empty signature can bypass the signature verification step. This could lead to unauthorized access and potential data breaches. Stay safe and update your libraries! #Authlib #Python #OAuth #OpenIDConnect #OWASP #API2 #CryptographyFailure https://lnkd.in/gYJQnJkV

Have you explored the critical Telnet vulnerability, CVE-2026-24061? It’s a fascinating case of environment variable argument injection that allows for complete authentication bypass. I recently built a Python script to demonstrate this exploit and set up a full testing lab using Docker. It was a great way to sharpen my Python automation skills and understand legacy protocol weaknesses. The Docker setup is incredibly straightforward—I highly recommend trying it out to understand the mechanics of the flaw. If you get stuck or want to discuss the exploit, feel free to DM me! https://lnkd.in/g3s-AVTd) #Telnet__Exploit #CVE #CVE_2026_24061

AutoPtT is a specialized tool for performing Kerberos Pass-the-Ticket attacks and ticket enumeration. Written in C++ and Python, it serves as a standalone alternative to Rubeus and Mimikatz. The tool offers functionality to list logon sessions, view tickets across sessions, export TGTs using LogonId, and import ticket files. It streamlines the PtT attack process through both automated and manual approaches. 🔗 https://lnkd.in/g6r6KnRh
